  2. 6. Beyond Gadgetry: Reflections on Tech- and User-Driven Research in Human-Computer Interaction

    Author : Pawel Wozniak; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; multi-device environments; spatial awareness; design-based research; designing for motivation; HCI as a field; big data; HCI for sports; mobile interaction;

    Abstract : This compilation thesis builds on a number of research projects within the domain of Human-Computer Interaction (HCI). Firstly, the thesis includes papers in the area of multi-device spatially-aware interactions. Prototypes of future interaction environments were built and evaluated in anticipation of technical developments in mobile sensing. READ MORE

  4. 7. The mechanical Paul trap in the upper secondary physics laboratory

    Author : Sebastian Kilde Löfgren; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physics education research; discipline-based education research; physics laboratory; design-based research; variation theory; model-based science; modelling; mechanical Paul trap; Paul trap.;

    Abstract : In physics, toy models are often used in popular science contexts. Further, toy models have also been used to communicate some important principles of abstract phenomena qualitatively. One such example can be found in the 1989 Nobel laureate Wolfgang Paul’s Nobel lecture. READ MORE

  5. 8. Low Phase Noise GaN HEMT Oscillator Design based on High-Q resonators

    Author : Mikael Hörberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resonator coupling; reflection oscillator; MMIC; phase noise; cavity resonator; low-frequency noise; GaN HEMT; MEMS;

    Abstract : The thesis considers the design and optimization of oscillators targeting low phase noise, given boundary conditions from the technology. Crucial technology figures are power capability, RF noise figure, low-frequency noise and the quality factor (Q-factor) of the resonator. READ MORE

  6. 9. Grouting of Fractured Rock with Silica Sol; Grouting design based on penetration length

    Author : Johan Funehag; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grouting; hydraulic test; sand column; propagation; penetration length; pipe flow; aperture; transmissivity; colloidal silica; silica sol; rheology; gelling liquids; field study;

    Abstract : ABSTRACTRecent grouting projects in Sweden have concentrated on the grout itself. The only grout normally used in Sweden is cement-based. During the past 10 years, the acceptable flow of water into tunnels has been reduced significantly. The current requirements mean that an average fracture aperture of around 0. READ MORE

  7. 10. Taming the Erratic : Representation and materialization in post-digital architectural design

    Author : Daniel Norell; Timothy Anstey; Ulrika Karlsson; Fredrik Nilsson; Claus Peder Pedersen; KTH; []
    Keywords : HUMANIORA; HUMANITIES; Representation; Materialization; Post-digital; Material simulation; Chunk; Arkitektur; Architecture;

    Abstract : This thesis investigates materialization and representation in contemporary architectural design practice. Due to cultural and technological shifts, the act of design is no longer squarely located in the abstract realms of drawings or digital geometries. READ MORE
